Consumer demand for ready-to-drink (RTD) beverages in the U.S. has grown considerably in recent years and is expected to reach $6.7 billion by 2019. The convenience of on-the-go drinks that are easy to drink while commuting or at the office is driving demand as is the desire for added nutritional values. Approximately one-quarter of beverages in many sectors now have protein, including carbonated soft drinks, bottled water, sports drinks, meal replacement beverages and more.
